A series of 3‐aryl‐4‐pyrrolyl‐maleimides were designed, synthesized, and evaluated for their glycogensynthase kinase‐3β (GSK‐3β) inhibitory activity. Most compounds exhibited potent activity against GSK‐3β. Among them, compounds 11a, 11c, 11h, 11i, and 11j significantly reduced Aβ‐induced Tau hyperphosphorylation, showing the inhibition of GSK‐3β at the cellular level. Structure–activity relationships

A series of 3‐(7‐azainodyl)‐4‐indolylmaleimides was designed, synthesized, and evaluated for their isocitrate dehydrogenase 1 (IDH1)/R132H inhibitory activities. Many compounds such as 11a, 11c, 11e, 11g, and 11s exhibited favorable inhibitory effects on IDH1/R132H and were highly selective against the wild‐type IDH1. Evaluation of the biological activities at the cellular level showed that compounds
A series of novel 3-benzisoxazolyl-4-indolyl-maleimides were synthesized and evaluated for their GSK-3β inhibitory activity. Most compounds exhibited high inhibitory potency towards GSK-3β. Among them, compound 7j with an IC50 value of 0.73 nM was the most promising GSK-3β inhibitor. Preliminary structure-activity relationships were examined and showed that different substituents on the indole ring and N1-position of the indole ring had varying degrees of influence on the GSK-3β inhibitory potency. Compounds 7c, 7f, 7j–l and 7o–q could obviously reduce Aβ-induced Tau hyperphosphorylation by inhibiting GSK-3β in a cell-based functional assay.
